Six stockpiles of aggregates (19.00, 9.50, 4.75, 2.36, 0.30, and 0.075 mm) were used to produce the base and modified asphalt mixtures, where stockpiles were coarse aggregates and others were fine aggregates. The Superpave uses the nominal maximum aggregate size (NMAS) of the aggregate to categorize mixtures and define graduation requirements.

Calculating Stockpile Capacity

2021-1-22  Calculating Stockpile Capacity: Once the minimum storage capacities which will assure maximum mill output are known, the appropriate stockpile configuration must be determined. Stockpiles fall into two general categories: conical and elongated. Conical Stockpiles The conical stockpile is the simplest and easiest to analyze. The total stockpile capacity is given by: 3.14 (Tan A)R³ D/3000
